Basketball is a team sport played by two teams of five players each, who score points by shooting a ball through a hoop. The rules of basketball can vary depending on the level of play and location, with professional rules differing from college rules, and international rules differing from USA professional rules. The majority of rules, however, can be applied to most games of basketball. The winner of a basketball game is the team with the most points, which can be scored by throwing the basketball through the opponent's hoop or basket. In regular play, a basket made within the three-point line is worth 2 points, and a basket shot from outside the three-point line is worth 3 points. Free throws are worth 1 point each. The rules of basketball cover equipment and facilities, regulations regarding teams, players, captains and coaches, playing regulations, violations, fouls and their penalties, special situations, and the officials and table officials.
| Characteristics | Values |
|---|---|
| Objective | Score by shooting a ball through a hoop elevated 10 feet above the ground |
| Game format | Two teams of five players each; two halves of 15 minutes each with a 5-minute break in between; if the score is tied, overtime periods are played until a winner emerges |
| Scoring | A basket made from within the three-point line is worth 2 points; a basket shot from outside the three-point line is worth 3 points; each free throw is worth 1 point |
| Ball movement | Players may only advance the ball by passing or dribbling (bouncing the ball on the floor); the player must dribble the ball with one hand while moving both feet; the ball must stay in bounds |
| Dribbling | A player can only dribble once and cannot start another dribble after stopping; if a player stops dribbling and then dribbles again, it is called a double dribble and the ball is turned over to the other team |
| Backcourt | Once the offensive team crosses half court, they may not go back into the backcourt (backcourt violation); if the defensive team knocks the ball into the backcourt, the offensive team can recover the ball |
| Fouls | Gaining an unfair advantage through physical contact; illegal contact, such as pushing, blocking, or striking another player, results in a personal foul; excessive contact results in a flagrant foul, which carries heavier penalties |
| Technical fouls | Violating the game's administrative rules, such as fighting or verbal abuse |
| Shot clock | Teams have a limited amount of time to shoot the ball during a given possession; in the NBA and WNBA, the limit is 24 seconds, while in NCAA, it is 30 seconds |
| Three-second rule | Offensive players cannot remain near their opponents' basket for longer than three seconds |
| Defensive rules | The main rule is to not foul; defensive players must actively guard an opponent within three seconds |
| Jump ball | The rule varies depending on the league; in the NCAA, the alternating possession system is adopted for all jump ball situations except at the beginning of the game |

Scoring points
The objective of basketball is for two teams to score points by getting the ball through the opponent's hoop, with the team scoring the most points being declared the winner. Teams must shoot the ball within a given time frame, with the NBA and WNBA allowing 24 seconds of possession, and NCAA teams allowing 30 seconds. The shot clock was introduced to increase the speed of play, and it resets when the ball touches the basket's rim or backboard, or the opponents gain possession.
There are two types of shots that can be made to score points: field goals and free throws. A field goal occurs when a player successfully shoots the ball into the basket during regular play. A basket made from within the three-point line is worth two points, and a basket shot from outside the three-point line is worth three points.
Free throws are shots taken from a stationary position and are usually taken after a foul has been committed. Each free throw is worth one point. The number of free throws awarded depends on the type of foul committed and the location of the player when they were fouled. For example, fouling a shooter will result in two or three free throws being awarded, depending on whether they were beyond the three-point line.
There are also rules in place to prevent players from gaining an unfair advantage near the basket. The three-second rule prohibits offensive players from remaining near their opponents' basket for longer than three seconds. Similarly, defensive players must actively guard an opponent within three seconds if they are positioned in the 16-foot lane or the area extending four feet past the lane endline.

Dribbling rules
Dribbling is a fundamental skill in basketball, used to advance the ball and create scoring opportunities. Here are the key rules pertaining to dribbling:
Basic Dribbling Technique
A player in control of the ball must dribble (bounce the ball on the floor) while moving both feet. If a player stops dribbling, they may only move one foot, which is called the pivot foot. The player must then pass or shoot the ball before their pivot foot returns to the floor.
Double Dribbling
A player is not allowed to dribble a second time after voluntarily ending their first dribble. This is called a double dribble and results in a turnover, with possession going to the opposing team. Once a player starts dribbling, they must continue until they pass or shoot the ball.
Carrying the Ball
The player's hand must be on top of the ball while dribbling. If the player touches the bottom of the ball or scoops it while dribbling, this is called carrying the ball. To be called a carrying violation, the player must also apply vertical lift, carry the ball horizontally, or allow it to come to rest in their hand and dribble again. Carrying the ball results in a turnover, with the ball going to the opposing team.
Backcourt Violation
Once the offensive team crosses half-court with the ball, they may not return to the backcourt. If a player in control of a dribble steps on or outside a boundary line, they cannot return inbounds and continue their dribble.
Gathering the Ball
When a player gathers the ball while progressing, they may take two steps before passing, shooting, or dribbling the ball. If the player has not yet dribbled, they may take one step prior to releasing the ball.
Pivoting
If a player stops dribbling and both feet are on the floor, they may pivot using either foot as their pivot. If a player jumps with both feet, they must release the ball before either foot touches the floor again.
These rules may vary slightly depending on the level of play and the specific league or governing body. For example, professional rules may differ from college rules, and international rules differ from those in the United States.

Fouls and violations
Fouls
A foul is an infraction that violates the rules of the game. A personal foul is a common type of foul, which involves illegal physical contact with an opposing player. This includes pushing, blocking, or striking another player in the act of shooting. If a defender fouls a shooter attempting a two-point shot, the shooter will receive two free throws. If a shooter is fouled during a three-point shot attempt, they will receive three free throws. If the player makes the shot they were attempting at the time of illegal contact, the basket counts, and the shooter will receive one free throw.
Excessive contact that could potentially injure an opponent is considered a flagrant foul and carries heavier penalties, such as fines, immediate ejection, and suspension.
An offensive foul is a type of personal foul committed by an offensive player when their team possesses the ball. Charging and illegal ball screens are common offensive fouls. Charging occurs when an offensive player makes contact with a defensive player who has their feet planted in a locked position. An illegal screen happens when a non-ball-handling offensive player moves while setting a screen for their teammate, hindering the defender's movement on the court.
Violations
A violation differs from a foul in that it does not involve physical contact with another player. A double dribble is a common violation, where a player starts dribbling again after stopping. This results in the loss of the ball to the other team.
The three-second rule is another violation, prohibiting offensive players from remaining near their opponents' basket for more than three seconds. This rule was introduced to prevent tall offensive players from gaining an advantage by waiting close to the basket.
Carrying, or palming, is similar to a double dribble and occurs when a player puts the palm of their hand under the ball or carries it in one hand for an extended period.
Other violations include travelling, kicking, and goaltending, which is when a player interferes with a shot when it is above the rim but still on its downward path to the basket.

Game structure
Basketball is a team sport played between two teams of five players each. The objective is to score points by shooting a ball through a hoop, with the team scoring the most points declared the winner. The game is played on a rectangular floor called the court, with a hoop at each end. The court is divided into two sections by a mid-court line.
The game is divided into two halves, with each half lasting 20 minutes in college basketball and 12 minutes in professional basketball. In high school and below, the halves are divided into eight or six-minute quarters. If the score is tied at the end of regulation, overtime periods of various lengths are played until a winner emerges.
Each team is assigned a basket or goal to defend, with the other basket being their scoring basket. At halftime, the teams switch goals. The game begins with one player from each team at the center court, with a referee tossing the ball up between the two. The player who tips the ball to a teammate starts the game. This is called a tip-off.
Once a team gains possession of the ball, they have 10 seconds to advance it over the mid-court line. If they fail to do so, the other team gains possession. The team with the ball is called the offense, and they can advance the ball by passing or dribbling. Dribbling involves bouncing the ball on the floor with one hand while moving both feet. If a player stops dribbling, they must either pass or shoot the ball and cannot resume dribbling. If the offensive team loses the ball out of bounds, the other team gains possession.
The defensive team aims to steal the ball, contest shots, and deflect passes. They must also be aware of foul rules to avoid penalties. A foul is defined as gaining an unfair advantage through physical contact, such as causing the offensive player to lose the ball or miss a shot.

Player positions
Although the rules of basketball do not define any specific player positions, there are five traditional positions that most teams have in their offensive and defensive schemes. These positions are part of an overall strategy, and many players today are interchangeable or can play multiple positions.
The first of these positions is the point guard. The point guard is the team leader and play-caller on the basketball court. They need good ball-handling skills, passing skills, leadership qualities, and decision-making skills. Point guards are typically the smallest player on the court.
The second position is the shooting guard. The shooting guard's main responsibility is to make long outside shots, including three-pointers. They should also be good passers and able to help the point guard with ball-handling. Shooting guards are often the top scorers on a team and tend to be larger than point guards.
The third position is the small forward. The small forward is often the most versatile player on the team. They should be able to help with ball-handling, make outside shots, and get rebounds. The combination of height and quickness allows them to defend a number of positions and take on the best scorer on the opposing team. Small forwards are typically larger than shooting guards but smaller than power forwards.
The fourth position is the power forward. The power forward is usually responsible for rebounding and some scoring in the paint. They should be big and strong and able to clear out space under the basket. Many great power forwards do not score a lot of points but lead their team in rebounds. They are often good shot-blockers as well.
The fifth and final position is the center. The center is usually the biggest or tallest member of the team. They can be big scorers, but they also need to be strong rebounders and shot-blockers. On many teams, the center is the final line of defense. Centers possess the ability to post up offensively, using pivot moves to hit a variety of shots. They are also known for protecting their own goal while scoring with high effectiveness.
